Persistence of outmoded concepts

Institutionalization of discriminatory outmoded concepts
Concepts which have been demonstrated to be inappropriate, incorrect or discriminatory are not immediately eliminated from institutional and other systems. Partly because they are associated with well-tried procedures, traces of them may persist in legal, educational, scientific, religious and other systems.
Concepts defined by some constituencies as outmoded may be of continuing significance to others. The concepts by which they are supposedly to be replaced may have latent defects they will subsequently make such replacement questionable.
